The streamWrapper class


Allows you to implement your own protocol handlers and streams for use with all the other filesystem functions (such as fopen(), fread() etc.).

Hinweis: This is NOT a real class, only a prototype of how a class defining its own protocol should be.

Hinweis: Implementing the methods in other ways then described here can lead to undefined behaviour.

An instance of this class is initialized as soon as a stream function tries to access the protocol it is associated with.

resource context

The current context, or NULL if no context was passed to the caller function.

Use the stream_context_get_options() to parse the context.

Hinweis: This property must be public so PHP can populate it with the actual context resource.


Version Beschreibung
5.0.0 Added the context property.
